BYD has gotten some attention since Warren Buffett has invested in them and they get mentioned at times on places like CNBC and various EV sites since they also sell EVs (including electric buses) and PHEVs, mostly in China.

Seems like in the US press, I only tend to hear about Tesla/Panasonic, LG Chem and Samsung SDI. AESC pretty much doesn't get mentioned except by Nissan and those who follow Nissan. I wasn't aware of Guoxuan High-Tech, Microvast nor Optimum Battery. Tianjin Lishen is certainly not a household name but sounded familiar. Apparently, they were the supplier to defunct Coda.

BYD just opened its third lithium-ion battery factory in China, which by 2020 will be world’s largest battery plant.

The new facility in lithium-rich Western China’s Qinghai province is ready to produce 24 GWh and step-by-step will be expanded to reach 60 GWh annually in 2020. The investment apparently already exceeds 10 billion yuan ($1.5 billion).

According to BYD, the factory in Qinghai will be largest in the world after its construction is completed in 2019 (equivalent to the size of 140 football fields).

At some point in 2014, AESC, which is also partly owned by NEC, became one of the largest electric vehicle battery manufacturers, second only to Panasonic, Tesla’s battery cell supplier. The joint-venture has since lost market share and Nissan has been quite open about looking to partner with someone else for future EV programs

China's CATL to build its first European EV battery factory in Germanyhttps://www.reuters.com/article/us-bmw- ... JZ11Y?il=0
"BMW plans to source 4 billion euros ($4.7 billion) of battery cells from CATL over the next few years, with 1.5 billion euros coming from the new site in Erfurt in eastern Germany, the carmaker’s purchasing head, Markus Duesmann, said. "

In the interim at least, Honda and GM are partnering to develop higher density battery packs for both GM and Honda BEVs. Both companies will use the same packs (or, I'm guessing, the same modules) according to the network TV report I saw. Here is a link I just now found:
